What detector to build according to search place

[cristiano.sar]

Im from Portugal but I'm living in Brazil.
Here in Brazil, for now, the places I can do metal detecting are beaches (I want to search for gold jewellery, etc) and in Portugal, fields like mountains (some mineralized, some not and I want to search for coins, maybe roman and other relics)

What detector you recommend me to build, is there one you recommend or have experience by using it in both kinds of fields, or one for each kind of situation/field?

The detectors in my list to build are:
- TGSL (re-building)
- Minipulse Plus Beach (building)
- Felezjoo (built)
- Delta Pulse (to build)
- Goldsan 5 lite (to build)

Tyanks.

Hi TGSL Good Working.

Hello Cristiano,

I find the GS4 from this YouTube video quite impressive! Since the GS5-lite has a very similar circuit but is easier to build, I would choose the GS5-lite.
Here is your link to the modified GS4. I think the secret of this GS4 lies in the good coil construction.

Thank you, I will make the GS5 lite and also trying to develop the Stm32 based one I wrote in the other post.
